Looks like due to all weather, the charter aircraft was late to CAK. Probably due to the arrival time and weather, they switched from PVD to BOS. Probably is empty to EWR but I'm sure they could have filled it with passengers from yesterday's flights. EWR had a horrible day with security breaches and weather.

A B-767-400ER is the last strech of the B-767-300ER. It is about 21' longer than the -300ER. Only two operators of the type, UA (PMCO) and DL. There was also one that was suppose to become the USAF E-10A, but that program was canceled and the airplane ended up being converted into a VIP airplane sold to someone in the ME.

A bit off topic, but why didn't DL use their 764s on longer routes when they first got them? My first flights on a 764 were in 2000 flying through SLC on the closing day of the winter olympics. Routed SLC-SFO-HNL-LAX then a few months later LAX-HNL-SLC. Is this like the 757 where airlines didn't realize the potential of the 757 for several years?
